Struct ConditionOption 

pub struct ConditionOption<T> { /* private fields */ }

Middleware for conditionally enabling other middleware in an Option.

Example

use actix_web::{App, middleware::Logger};
use actix_web_lab::middleware::ConditionOption;

let normalize: ConditionOption<_> = Some(Logger::default()).into();
let app = App::new().wrap(normalize);

Trait Implementations

impl<T: Debug> Debug for ConditionOption<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> From<Option<T>> for ConditionOption<T>

fn from(value: Option<T>) -> Self

Converts to this type from the input type.

impl<S, T, Req, BE, BD, Err> Transform<S, Req> for ConditionOption<T>

where S: Service<Req, Response = ServiceResponse<BD>, Error = Err> + 'static, T: Transform<S, Req, Response = ServiceResponse<BE>, Error = Err>, T::Future: 'static, T::InitError: 'static, T::Transform: 'static,

type Response = ServiceResponse<EitherBody<BE, BD>>

Responses produced by the service.

type Error = Err

Errors produced by the service.

type Transform = ConditionMiddleware<<T as Transform<S, Req>>::Transform, S>

The TransformService value created by this factory

type InitError = <T as Transform<S, Req>>::InitError

Errors produced while building a transform service.

type Future = Pin<Box<dyn Future<Output = Result<<ConditionOption<T> as Transform<S, Req>>::Transform, <ConditionOption<T> as Transform<S, Req>>::InitError>>>>

The future response value.

fn new_transform(&self, service: S) -> Self::Future

Creates and returns a new Transform component, asynchronously
